This question was directly addressed in the episode Birthright, Part 1: BASHIR Data... may I ask you a personal question? DATA Certainly. BASHIR Does your hair grow? Data thinks a moment, taken aback by the question. DATA I can control the rate of my ...

In the second season episode "The Measure of a Man", Riker pulls up Data's schematics on a wall monitor. On the lower right of the display, we see "LT CDR NFN/NMI DATA" which should be read as "Lieutenant Commander No First Name No Middle Initial Data." This was confirmed by illustrator Rick Sternbach during the "Next Generation Slide Show" panel at Baycon ...

They are playing three-dimensional chess, which may involve many more permutations for a small number of moves than ordinary 2D chess--even the best computer programs still can't typically beat professionals at the game of Go for example, because the number of permutations is much larger than in chess. We also don't know if Data was programmed to do brute-...

I wouldn't overanalyse this too much - it's just a case of bad writing. Furthermore, it was written in the early 90s, back before computers surpassed humans at chess, and people still thought that magical human intuition could beat brute force calculation every time. Really, the ludicrous part is the idea that a 'classic attack', which has apparently been ...

Because it's complex and not a good idea. In "A Fistful of Datas" exactly that is tried. It resulted in a mix-up of Datas thoughts and ideas with the computers database almost crippling the ship. Data in turn was "infected" with gun-slinger personality-traits from a program running on the holodeck. LAFORGE: We think our interface experiment may have ...

Because Troi is not playing the way Data expects From the transcript: (a 3D chess game is in progress) DATA: The characteristic response to the Kriskov Gambit is to counter with the el-Mitra Exchange, particularly since I have already taken both your rooks. By missing that opportunity, you have left your king vulnerable. TROI: We'll see. ...

Data was doing exactly what he wanted to do. It was his desire to be treated as a human. He wanted to be a Starfleet officer, serving with humans on a team. He did not want to be used as a tool. There were those in Starfleet that wanted Data for other things, arguing, just as you are, that Data's potential was wasted as a simple Starfleet officer. (See ...

Data's lack of emotions is intentional According to Lore, Dr. Soong deliberately left many features out of Data's programming in a bid to make him less threatening to humans. LORE: It would be foolish to underestimate you, brother. Yes, I lied when I said you were made first, but with good reason. Doctor Soong made me perfect in his first attempt. ...

Data did grow a beard at one point (TNG: "The Schizoid Man") so I guess he needs to cut his hair. Alternatively, he can chose when to grow the hair or the beard. After some search I found that in episode "Birthright, Part I" (at 11:05), he says he can control the rate of his hair growth. So judging from that information, it probably means he may need to ...

Prior to the 12th episode of the series, Datalore, Data did use contractions. In Datalore, his tendency not to use them was pointed out by Lore: Haven't you noticed how easily I handle human speech? I use their contractions. For example, I say "can't" or "isn't". You say "cannot" and "is not". However, at the end of the episode, Picard asks: Are you ...

Just remember these lines at the end of "All Good Things" (from the transcript here): CRUSHER: You know, I was thinking about what the Captain told us about the future. About how we all changed and drifted apart. Why would he want to tell us what's to come? LAFORGE: Sure goes against everything we've heard about not polluting the time line, ...

Salvage Law Data was found inactive on the surface of a planet that had been stripped of life. While we don't have the exact text of the Federation's version of Salvage Law, it is known from an episode of Deep Space Nine that abandoned technology on a lifeless planet can be claimed by its finder. This is consistent with maritime salvage laws. Inheritance ...

Data has artificial hair follicles. They can (presumably) take nutrients from what he consumes and convert those into a hair-like substance. BASHIR: Does your hair grow? DATA: I can control the rate of my follicle replenishment. However, I have not yet had a reason to modify the length of my hair. Why do you ask? TNG: Birthright, Part I


52

Why is Data so “unique”? He's an android Your other example is a ship's computer, and they are absolutely huge. This is what the core of Voyager's computer looks like (from Concerning Flight) compared to a normal person: And the Enterprise's computer is shown to be a huge room where the walls are the computer cores in Evolutions: This is made even more ...

Data's hair definitely does not require trimming. In the episode "Data's Day", Data visits the barber shop while Geordi is getting his own cut. He tries out the following joke with Geordi: My hair does not require trimming you lunkhead! Even though Data is not the best at jokes, this definitely implies that Data does not need the services of the ship ...

At first glance, Data does seem to use his mouth (i.e. lips and tongue) to speak, which suggests that he's using some kind of larynx-like expiration-based voice generation system, otherwise, his lip/tongue configuration would not modify the sound much. However, we also know that Soong deliberately made Data superficially emulate many humanoid functions, ...

A normal holodeck actually does have physicality - or rather, it can. When a human (or other physical being) enters the Holodeck, it has to make some of the features 'solid'. From Memory Alpha's "Holodeck" entry: A holodeck combines elements of transporter technology with that of replicators, by generating actual matter, as well as projecting force ...

TL; DR - Data can forget things when deletion is justified This started as a summary, but got a bit long! Anyway, below I present evidence that Data can forget things through hardware manipulation, but this doesn't seem to be in the spirit of the question which implies Data forgetting something through software means. If we interpret the question in this ...

In the 7th season episode "Inheritance" we find out that Data has a modesty subroutine. When Data was first constructed, he didn't feel the need to dress because he didn't "suffer from the elements", but some of the colonists were disturbed because he was anatomically correct. Data would not willingly change into the clothes that Fajo wanted him to wear ...

I believe its an homage to Asimov's Robot stories, where the robots were always being described as having Positronic Brains. Asimov just picked "Positronic" because it sounds high tech, and never attempted to actually describe how they work in any detail.


45

Data most certainly does NOT follow the three laws of robotics. Data is a serving officer in the Federation's military, he gives as well as takes orders. If he were to follow the Second Law of robotics, even enlisted personnel could force him to follow their orders. Data ignores the Third Law, he could not have acted as he did at the end of Nemesis - ...


43

The test would be valid for him. Even though he cannot feel fear, it would still determine how focused under pressure he would be. Even an unemotional android could freeze under pressure. The test was, after all, designed by a Vulcan, under the assumption that other Vulcans might take it. That being said, I think Data would have done quite well, ...

In the movie First Contact the queen actively attempts to assimilate/turn Data into a Borg, by giving him skin implants that allow him the real sensations of a biological being, thus tempting Data. The Borg are unable to assimilate Data as he is technically more advanced than they are mechanically, however Data can choose to join the Borg and he would then ...


42

Because Data was of a lower rank! Data was a Lieutenant Commander and Troi was promoted to Commander. Simply put, the ranking of Commander outranks Lieutenant Commander. Data was speaking technically that Troi outranked him - because Troi was a Commander, a higher rank, she could give him an order. You are getting confused with the chain of command on ...

I doubt he would need to He certainly seems to memorize everything. From S03E03: Doctor Beverly Crusher: Could I have your names, please, just for the record? Rishon Uxbridge: I'm Rishon Uxbridge, and this is my husband Kevin. Lt. Commander Data: Botanists. Originally from the aquatic city New Martim Vaz in Earth's Atlantic Ocean. ...


41

The screen direction in the original script indicates that Data was simply unable to read the label. Since the earlier direction is that the bottle is "very old" the implication would be that the label is decayed rather than that he doesn't speak the language. He smells it but is unfamiliar with the scent. Data bends down and reaches under the bar... ...

From the transcript of Insurrection: ARTIM Don't you ever get tired? DATA My power cells continually re- charge themselves. So he is powered by "power cells" that continually recharge themselves, therefore ...

The events in All Good Things were the result of Q playing around with reality (or possibly just Picard) by moving things backwards, forwards, and sideways through time. The presence of Q and his usual shenanigans means that all bets are off as to what is real, what isn't real, what will be real, and what might become real. The future events in All Good ...

Kivas Fajo suggests that Data will probably follow the rules of decency prescribed by Starfleet training: FAJO: Oh, don't worry. The solvent won't harm your, your skin. But in seconds it will completely dissolve that uniform. Personally, I'd be delighted to see you go around naked. I assume you have no modesty. But, then, I guess that decency is the rule ...

Data often strives to emulate humans - this likely goes as far as to try and play chess like a human rather than like a computer. The episode "Peak Performance" actually goes into this; Data is soundly beaten at the game Strategema by an expert. Data is given advice to stop trying to play like others do and instead use his own strengths - in the rematch, ...
